mmo + dextron + gasoline = ?

[mdocod]

I seem to recall reading somewhere on here that a good home-brew fuel addative for cleaning and lube, is to mix mmo and auto-transmission fluid in with the gas. (somewhere around 0.5oz of each per gallon of fuel)... I searched back aways and didn't find it, does this ring a bell with anyone?

Is it a good idea? does this homebrew idea even exsist?

I've been using mmo religiously for about a month now (~2000 miles)(it's a new religion, but i've taken to it well). started with a "shock" dose and have pretty much been sticking close to the recomended dose since then. Bought a 1 gallon jug of it at Walmart that I am using to refill the 32oz size bottle (has measurements on the side). I haven't really noticed anything- but after doing a seafoam cleaning on my intake it seemed like a good idea to start running something that would keep deposits under control. On an engine with 175k on it, anything I can do at this point to keep it going for a reasonable price seems worth a shot...

Then the other day as I was pulling my mmo out of the "box" in the back, my eye cought a bottle of Dexron that has sat in there for about 6 months. I bought it with the intention of having it on hand if my power steering ever got low, and it never has, so now i've got this Dexron lookin me in the face. and the question pops to mind- maybe I should put it in the tank?

and then- i realized, i have been totally mispelling (and mis-saying) "DEXRON" and that totally limited my search results to "0."

I found some stuff...

everything from "ATF is similar to fuel cleaner" to "ATF contains very little detergency" to "ATF is terrible for the engine and will cause buidup" to "ATF was used in the 70s by gm as a carbom remover- apply to intake through a booster line similarly to seafoam or water treatments" to "it smells good."

so- um. idunno- should I use it or not- 1995 isuzu rodeo, 3.2L V6, 24 valve, SOHC.

I'd quit using ATF.
The Marvel Mystery oil may have benefits, however.

A long time ago I had an old Chevy station wagon with an automatic transmission. The engine ran pretty bad when I first got it and the transmission worked perfect. Soon after the transmission stopped shifting correctly and the engine started running great. A modulator valve on the transmission which receives a vacuum signal from the engine failed and transmission fluid got sucked into the intake manifold, a lot of it. I replaced the modulator valve and the engine ran great and the transmission shifted ok again. So it looked like my transmission gave my engine a tune-up.
